PIC_RS232

说明：  OLED显示屏测试，基于IIC通讯，供电3.3V或5V(OLED screen display demo)

该电源以单端反激式DC-DC变换器为核心。市电通过自耦式调压器，隔离变压器，整流滤波后产生直流电压，经DC-DC变换得到题目所需输出电压，实现了开关稳压电源的设计。(The power to single-ended flyback DC-DC converter at the core. City through the auto-type voltage regulator, isolation transformer, rectifier filter DC voltage generated by the DC-DC conversion has been the subject output voltage required to achieve a switching power supply design.)
